Patent DE-3424925-C1 (DE)
Title: Turbo engine with at least one radial flow rotor
Inventor: GOLDBERG KLAUS
IPC: F04D29/44
Filed: 1984-07-06
Granted: 1985-10-17
Abstract: In a turbo engine of radial type, for example a radial compressor, diffusers (11, 12, 13) joined onto the periphery of the rotors (5, 6, 7) are provided, which comprise two parallel, annular outer discs (14, 15) with guide vanes (16) lying between them. In order to prevent sympathetic vibrations in operation and to improve the strength, especially in order to prevent weak points, for example weld seams, screw fastenings etc., the guide vanes 16 are loosely inserted in slots of the one outer plate with a certain play so that they perform more or less uncontrolled movements and cannot start to resonate owing to the high damping. <IMAGE>

IPC: F23D11/02
Filed: 1991-09-27
Granted: 1992-10-15
Abstract: A burner suitable for heating a furnace chamber of an industrial furnace which is equipped with a recuperative preheater for combustion air has a combustion chamber at one end and a feed-through cap at the other end which is accessible outside of a furnace in which the burner is installed. The tubular recuperative preheater is of the coaxial countercurrent flow configuration extending between the combustion chamber and an annular outflow collector cap. A coaxial fuel pipe is centered in the burner extending to the combustion chamber. Overheating of the burner cap is prevented by means of a spacer sleeve of small heat conductivity interposed between the preheater and the burner cap. This permits the valves to be seated in the burner cap without risk of thermal damage. For protection of personnel against contact with hot surfaces, a perforated metal shield is provided between the burner cap and the outflow cap of the recuperator, essentially covering all the portions of the burner outside a furnace wall.

Title: Analyte concn. measuring method, e.g. for medical blood diagnosis
Inventor: NIESNER REINHARD DR
IPC: G01N21/3504
Filed: 1994-12-23
Granted: 1996-07-04
Abstract: The method uses a spectrometer with at least two laser diodes IR sources. One diode emits radiation at a wavelength which the analyte strongly absorbs, while the other emits radiation at a wavelength which the analyte weakly absorbs or does not absorb. The injection currents of the laser diodes are amplitude modulated and have a phase shift of alpha = 180 deg. The radiation intensities directed towards a transmission cell have a corresp. time dependence and phase shift. Every change in concn. of the analyte changes the match between the modulation amplitudes of the diode currents. The DC current of the detector is then superimposed on the signal components containing the modulation frequency. The amplitude and phase of the signal components indicate the increase or decrease in analyte concn.

Flux-density transformer is built in active zone of transducer 3 and reference signal is built up across its output. This signal goes via follower 4 to inverting input of differential amplifier 2 to shape feedback signal of this amplifier. Amplifier gain does not depend on equivalent parameters of flow transducer field circuit and depends only on feedback circuit characteristics. EFFECT: reduced power loss. 2 cl, 2 dwg
